Mamuang,
Glad to hear your Hosui perform well for you.
I have Hosui too but it ripens between early to mid August for me while the weather is still hot. By hot I mean high’s around low 90’s on some days. If I were to have a crunchy Hosui, I need to pick when there is still some green color on it even though it’s still not at its sweetest. If I were to wait till the whole pear turn brown, it would not be crunchy anymore though very sweet. I blame it on the temperature but really don’t understand it because low 90’s are not supposed to be that hot for pear. At least it does not affect 20th Century which ripens around the same time.
Unfortunately 20th Century has never been my favorite because it’s not sweet enough. I have just grafted Shinseiki on my tree a few months back. If the shoot continue to stay healthy and not attacked by FB, I can send you scionwood in winter.
Another variety you might want to try is Ichiban. It ripens about 2 weeks earlier than Hosui/20th Century in my area which is kind of nice to have around to stretch the pear season.
I agree, if you don’t consider thinning and bagging as work. For some reason, squirrels do not seem to bother them most years. They would rather attack my Jiro persimmons which are not even close to ripe and most are still completely green.
